Abstract

Infrared femtosecond laser has highly spatial coherence, and order walk-off will happen behind the phase mask. In this paper, the interference patterns in the core are modeled by using two beam interference theory, and fiber Bragg gratings are fabricated in the unphotosensitive Tm-doped fibers using 800 nm femtosecond radiation. In the end, the simulative results are compared with the experimental results.
